Whelan scored his second international goal against Italy on Saturday
Glenn Whelan is a doubt for Stoke City's home game against West Ham on Saturday after hurting his calf whilst on duty with the Republic of Ireland.
The 25-year-old was injured in the 2-2 draw against Italy at Croke Park, after scoring the opening goal of the game.
"We're not sure to what extent he's injured at the moment," Stoke coach Mark O'Connor told BBC Radio Stoke.
"I'm expecting him in on Tuesday, so we'll assess his fitness and we hope he's going to be fit for the weekend."
Whelan is suspended for Ireland's final World Cup qualifier, which is against Montenegro in Dublin on Wednesday.
They both acquitted themselves well and the future looks bright for them
His Stoke team-mate, Liam Lawrence, also started against Italy, and O'Connor said that both players did their club proud with their performances.
"I'm very pleased for them and the goal capped it off for Glenn. It was a magnificent goal," he added.
"They both acquitted themselves well and the future looks bright for them. They've got the play-offs to come and then hopefully the World Cup."
Goalkeeper Thomas Sorensen will be at the finals in South Africa in 2010 with Denmark, becoming the first Stoke player since Northern Ireland's Sammy McIlroy in 1982 to represent his country on football's biggest stage.
